+The gga_load_data tools allow automated deployment of GMOD visualisation tools (Chado, Tripal, JBrowse, Galaxy) for a bunch of genomes and datasets. 
 They are based on the Galaxy Genome Annotation (GGA) project (https://galaxy-genome-annotation.github.io). 
-A stack of Docker services will be deployed for each organism. 
 
-## Description
+A stack of Docker services is deployed for each organism, from an input yaml file describing the data.
+See `examples/example.yml` for an example of what information can be described and the correct formatting of this input file.
 
-Automatically generates functional GGA environments from a descriptive input yaml file.
-See `examples/example.yml` for an example of what information can be described
-and the correct formatting of this input file.
+Each GGA environment is deployed at [https://hostname/sp/genus_species/](https://hostname/sp/genus_species/).
 
-The "gga_load_data" tool is divided in 4 separate scripts:
+## Reverse proxy and authentication
+
+Traefik is a reverse proxy which allows to direct HTTP traffic to various Docker Swarm services.
+The Traefik dashboard is deployed at [https://hostname/traefik/](https://hostname/traefik/)
+
+Authelia is an authentication agent, which can be plugged to an LDAP server, and that Traefik can you to check permissions to access services.
+The authentication layer is optional. If used, the config file needs the variables `https_port`, `auth_hostname`, `authelia_config_path`.
+
+Authelia is accessed automatically by Traefik to check permissions everytime someones wants to access a page. 
+If the user is not logged in, he is redirected to the authelia portal. 
+Note that Authelia needs a secured connexion (no self-signed certificate) between the upstream proxy and Traefik (and https between internet and the proxy).
+
+## Steps
+
+The "gga_load_data" tools are composed of 4 scripts:
 
 - gga_init: Create directory tree for organisms and deploy stacks for the input organisms as well as Traefik and optionally Authelia stacks
 - gga_get_data: Create `src_data` directory tree for organisms and copy datasets for the input organisms into the organisms directory tree
